I watched the video all the way through. Personally I think that thing is ridiculous and he's ridiculous. He speaks as though you can't travel this world safely in anything less. It's kind of silly the idea that he's building it with his daughter in mind. I grew up camping with my family and grand parents in the back country like a lot of people have for generations. Camping in a tent, sleeping on the ground, eating canned beans, playing in the dirt. Yeah sure, that monstrosity is EXACTLY what your daughter needs.
To each his own.
